' FOUNTAIN-PEN.

Specification of Letters Patent. 7 Patented Dec, 10, 1912.

Application filed May 22, 1912. Serial No. 699,044.-

The object of the invent-ion is to provide a duplex fountain pen whichshall be simplev in structure, easy of operation and especially handyfor traveling men and others who desire to use different colored inks.

In the embodiment of our invention we provide a tubular barrel having aplurality of reservoirs longitudinally slidable therein.

Each reservoir carries on its lower-end a pen point and feeder and thereservoirs are so connected that when one pen point is being used theother will be disposed with the barrel or casing.

The invention consists in certain novel constructions and arrangement ofparts, as we shall hereinafter fully describe and claim.

For a complete understanding ofour invention reference is to be had tothe following description and accompanying drawing, in which Figure l isa side elevation of our improved pen. Fig. 2 is a longitudinal sectionalview, partly in elevation. Fig. 3 is a perspective View of the divisionplate. Fig. 1 is a transverse sectional view on line 4-4 of Fig. 2. Fig.5 is a-longitudinal sectional view showing a modified form of ourinvention. Fig. 6 is a longitudinal sectional view, partly in elevation,showing another modification.

Referring more particularly to the drawing by numerals, 1 designates thetubular barrel or casing, the inner wall of which is provided with theoppositely disposed longitudinal grooves 2, which receive the edges ofthe division plate 3 and hold the same in position. The plate dividesthe barresiding at Logan, in the 6 of each reservoir is detachable,being screwed to the main portion, and is provided with the pen point 7and feeder 8 of the usual construction. The reservoirs may be filledthrough the top after removing the threaded plugs 9.

10 is a small hole for the pur ose of admitting air as t e ink isconsumed When one reservoir is being used its pen point extends entirelywithout the casing and the other reservoir and pen point are housedwithin the casing. Removable caps 11 close the ends of the said casing.

The upper end of the partition plate 3 is enlarged as shown at 12 andformed with a transverse slot 13. A grooved roller 14- is held withinthis slot by the screw 15 which passes through the enlargement 12 atright angles to the slot 13 and has its head counter-sunk and its endthreaded, into the barrel 1. chain 16 connected at its ends by swivels'17 .to the plugs 9 passes over the roller 14, the roller being spacedfrom the top of the slot 13. v

The upper end of the barrel 1 is cut away on opposite sides of thedivision plate 3' to form the end opening recess 18' the purpose ofwhicliwill be hereinafter explained.

A small flat metal spring 19 extends through a slot 20 in the lower endof the partition plate 3 and has its end portions 20 bent upwardly onoppositesidesof theplate 3 and secured thereto. The spring is for thepurpose of holding reservoir 4 or 5 immovable when in use and is sopositioned that simultaneous engagement with both reservoirs isimpossible. As shown in Fig. '2 the reservoirs 4c and 5 are of such asize that they may be easily moved past the ends 20' of the metal spring19, but if desired said ends may be sunk in the partition,

3 and made to lie flush with the same, in which case the reservoirs maybe made of such size as to fit. snugly within the barrel.

' said reservoir is forced, by pressing in the upper exposed end of thesame, longitudinally of the barrel toward the lower end thereof; Thissliding movement brings the reservoir into frictional engagement withthe spring19'aud' automatically draws the.

reservoir 5 to the top of the casing 1 and away from engagement withsaid spring.

The chain 16 running over thepulley 14 furnishes the means of raisingone reservoir when the other is lowered.

From the foregoing description in connection with the accompanyingdrawing it will be seen thatwe have provided 'a duplex fountain pen ofsimple construction, compact form andrnovel arrangement of parts.

It is to be understood that our invention may be constructed of anysuitable material and that slight modifications may bemade site sides ofthe division plate and having a central portion working in a slot in thenately engage the reservoirs.

In testimony whereof We hereunto affix our signatures in the presence oftwo witnesses.
